Abstract

The main purpose of this project is the development of an integrating methodology to select the most appropriate chemotype and extraction method for obtaining mint extracts (Mentha sp.) with antimicrobial/antifungal activity, for potential use as natural biocides for food use. Advances in different aspects are proposed for this, including: (i) the optimisation and development of advanced mint extraction and bioactive component analysis. (ii) The development and validation of several methodologies (conventional and metabolomic focus) for the study of chemotypes in mint. This aspect is of great relevance for the standardisation and control of bioactive extracts with potential usage on an industrial scale. (iii) Lastly, we will attempt to establish possible relationships between the composition of extracts and their bioactivity, which would be useful for selecting the most interesting extracts from the perspective of their potential industrial exploitation.
